4WD HIGH TEMP IS DISPLAYED ON INFORMATION DISPLAY
Description
INFOID:0000000010755292
While driving, 4WD warning (4WD High Temp. Stop vehicle) is displayed on information display (combination
meter).
• This symptom protects drivetrain parts when a heavy load is applied to the electric controlled coupling and
multiple disc clutch temperature increases. Also, optional distribution of torque sometimes becomes rigid
before 4WD warning (4WD High Temp. Stop vehicle) is displayed. Both cases are not malfunction. Refer to
.
• When this symptom occurs, stop vehicle and allow it to idle for some times. Displays will stop and system
will be restored.

Diagnosis Procedure
INFOID:0000000010755294
1.
CHECK TIRE
Check the following.
• Tire pressure
• Wear condition
• Front and rear tire size (There is no difference between front and rear tires.)
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Repair or replace error-detected parts. And then, drive the vehicle at speed of 20 km/h (12 MPH)
or more for 5 seconds or more. Improper size information is initialized accordingly.
2.
CHECK INPUT SIGNAL OF TIRE DIAMETER
With CONSULT
1.
Start the engine.
2.
Drive at 20 km/h (12 MPH) or more for approximately 4 minutes continually.
3.
Check “DIS-TIRE MONI” of CONSULT “DATA MONITOR” for “ALL MODE AWD/4WD”.
Does the item on “DATA MONITOR” indicate “0 - 4 mm”?
YES
>> INSPECTION END
NO
>> GO TO 3.
3.
TERMINAL INSPECTION
Check 4WD control unit harness connector for disconnection.
Is the inspection result normal?
YES
>> Replace 4WD control unit. Refer to
DLN-72, "Removal and Installation"
NO
>> Repair or replace the error-detected parts.
